Thanks, that does sound the easiest way, although it apparently needs water to work (a bit like bran maybe?), so I can perhaps just add a bit of extra water over the food...
I bought it in a bit of panic as Humphrey‘d eaten a bit more bone than normal and I was worried he‘d get a bit constipated. (Been watching too many vet programmes!
) There are loads of websites praising its benefits but unfortunately a lot of them make a bit of a science out of administering it,!!>
Thanks
